Hi everyone, My name is Bill, I have been out of the hobby since 2005 when we moved. At the time I had a glass 100gal reef tank, w 20 gal sump. I looking to get back in, but realize things have probably changed some (maybe a lot) since then. Looking to setup another reef tank, between 75 - 125gal. New lighting techniques, filtration, lots of changes and looking for ideas so that I don't make major mistakes.
